Abstract
The utility model relates to a packing auger bearing, which comprises a bearing seat provided with a grease hole, a pair of oil sealing press covers, a pair of frame type oil sealing seal circles, a pair of dust prevention press covers, a pair of dust prevention seal circles, two groove rings for roll balls and a plurality of roll balls, wherein the dust prevention seal circles are composed of elastic wear-resistant fabric washers and springs, the springs are arranged at the periphery of the wear-resistant fabric washers, and a material pad circle is tightly butted so as to give radial tight press. The washer abrasion can be made to obtain compensation through spring action of the bearing. For example, when a wool felted washer is adopted, the radial compensation thickness of the wool felted washer can reach 4 to 5 mm, the seal effective period is made longer, the dust prevention effect is good, and the use is more reliable.
Description
The utility model relates to the bearing that is used to carry the rotating shaft Radial load in a kind of spiral powder conveying machine.
Spiral powder conveying machine as powder product load transfer devices such as coal dusts, because it moves in dust atmosphere, require the bearing of rotating shaft to have oil sealing and dust reduction capability, therefore the spiral powder conveying machine bearing is provided with a pair of oil sealing seal ring and a pair of dust-proof seal ring, inboard oil sealing seal ring prevents that the interior oil of bearing is to external leakage, the dust-proof seal ring in the outside prevents that extraneous dust from entering bearing, to guarantee the bearing normal operation.At present, the oil sealing packing ring and the dust collar of spiral powder conveying machine bearing all adopt the skeleton type packing ring, and the skeleton type seal ring is vulnerable to the erosion and the wearing and tearing of material, influences sealing effectiveness, cause dust to be invaded, and influence the bearing normal operation.
The purpose of this utility model provides a kind of spiral powder conveying machine bearing, and it is easy to wear and be subject to dust erosion and the adverse consequences that causes that it can overcome dust-proof seal ring effectively, guarantees that bearing keeps excellent sealing performance.In addition, have at bearing under the situation of above-mentioned excellent sealing performance, internal gas was discharged smoothly when the utility model can also make bearing refuel, and was full of the bearing abdominal cavity with the fluid of guaranteeing to add.
The utility model spiral powder conveying machine bearing comprises the bearing seat that is provided with oil hole, a pair of oil sealing gland and skeleton type oil sealing seal ring, a pair of dustproof gland and dust-proof seal ring, two ball grooved rings and a plurality of ball, said dust-proof seal ring is made up of elastic wear-resisting fabric packing ring and spring, spring is located at the periphery of elastic wear-resisting fabric packing ring, and is tight against this packing ring and gives radial compaction power.When packing ring was worn, spring still can make it be tight against rotating shaft, reaches sealing effectiveness.The utility model also has the oiling damping and shows oilhole on bearing seat.This hole makes the Intraabdominal gas of bearing communicate with the external world, and the chamber inner fluid is had shock damping action.
In sum, in the utility model bearing, dust-proof seal ring can make the wearing and tearing of bedding and padding circle be compensated by the effect of spring, for example adopts the wool felt packing ring, and its radial compensation thickness can reach 4-5mm, makes the sealing subject word longer, and dustproof effect is good.Gas discharge in abdominal cavity when oilhole can make oiling is shown in the oiling damping of setting up on the bearing seat, and oil circuit is smooth and easy, remedies because of sealing the good oil circuit retardance that causes, this hole shows functional oil in addition, promptly whether there is fluid to ooze, judges in the bearing abdominal cavity and whether fill with, therefore use more reliable by the aperture.
Below in conjunction with description of drawings example structure of the present utility model.
Accompanying drawing is represented the cross-section structure of this spiral powder conveying machine bearing.
As shown, the upper end of bearing seat 1 is provided with oil hole 12, and the lower end is provided with the oiling damping and shows oilhole 14.This hole 14 also can be located at the bearing seat appropriate location as required.Be arranged with a plurality of balls 3 between the two ball grooved rings 13, grooved ring 13 is connected with rotating shaft 9 by the back-up ring 8 at two ends, oil sealing seal ring 7 is skeleton type seal rings, the 2nd, the oil sealing gland, wool felt packing ring 6 and spring 5 are formed dust-proof seal ring, spring 5 radial compaction wool felt packing rings 6, dustproof gland 4 is provided with anti-rotating pin 11 with wool felt 6, and packing ring 6 can not be rotated with axle.When axle 9 together rotates by back-up ring 8 drives two grooved rings 13, grooved ring 13 and the interior ball 3 generation friction of rollings of groove.When from oil hole 12 in bearing during oiling, the gas in the bearing can show that oilhole 14 discharges by the oiling damping, makes fluid be able to smooth injection, when the aperture had oil droplet to go out, expression oil was filled with i.e. stop oiling.The shock damping action of these 14 pairs of fluid in hole can be realized by adopting suitable small-bore or adding the lid or the plug that have aperture in the aperture.
Claims (2)
1. spiral powder conveying machine bearing, comprise the bearing seat that is provided with oil hole, a pair of oil sealing gland and skeleton type oil sealing seal ring, a pair of dustproof gland and dust-proof seal ring, two ball grooved rings and a plurality of ball, it is characterized in that said dust-proof seal ring is made up of elastic wear-resisting fabric packing ring and spring, spring is located at the periphery of elastic wear-resisting fabric packing ring, and is tight against this packing ring and gives radial compaction power.
2. according to the described spiral powder conveying machine bearing of claim 1, it is characterized in that having on the bearing seat oiling damping and show oilhole.
